About

I'm Stan Angeloff — CTO by day, tinkerer by heart. Based in Sofia, Bulgaria. I run the tech at Luup. This blog is my personal space for thoughts, rants & research.

◆What I'm up to (2025—)

Most of my free time goes into Flemma — a low-level AI workspace that runs inside Neovim. Not a wrapper, the actual thing: streaming APIs, tool execution, prompt pipelines, talking to Anthropic, OpenAI and Google directly. I built it because I needed it for work — PRDs, statements of work, R&D spikes, client documentation. Every feature exists because a real problem demanded it.

The core belief: models come and go, but the workspace you build around them is yours. Go one level lower than you think you need to. Write your own agents, wire up your own tool execution, parse your own streaming responses. The best way to understand AI tooling is to build it yourself.

I'm also experimenting with Voxize, a voice-to-text tool for Linux/Wayland — my daily driver for AI-assisted coding instead of reaching for the keyboard.

◆Technical background

I've been at this for over two decades, touching just about everything along the way. Some highlights from the archives:

CoffeeScript — used to be a top 10 contributor to jashkenas/coffeescript (now sitting at #9, but who's counting)
Ruby — built compass-magick and compass-canvas, dynamic image generation in pure Sass
PHP — created php.vim, the community-standard Vim syntax for PHP (473+ stars)
JavaScript — built Zoey, a lightweight mobile app framework, and Lotte, headless browser testing with PhantomJS before Puppeteer existed
Shell & terminal — a big believer in open, free, terminal-based tools. Built vagrant-shell-scripts back when provisioning VMs was the thing to do
GitOps — managed all my PCs with Ansible for years, even gave a talk about it back when Ansible was the underdog. Now I run NixOS

TypeScript, Node.js, and whatever else the job demands — I've never been one to stick to a single stack.

◆The honest bit

As you can tell, most of those projects are pretty old. I haven't been as active in the OSS community as I'd like — but I'm still here, still tinkering, and Flemma is where that energy goes now.
